Question 1

What is BREEAM?

Answer 1

Building Research Establishment Environmental Assessment Method:
- It is a sustainability assessment method
- It sets standards for the environmental performance of buildings through design, specification, construction and operation phases

Question 2

What are the three pillars of sustainability?

Answer 2

• Social
• Economic
• Environmental

Question 3

What are the different levels of BREEAM?

Answer 3

• Unclassified Less than 30%
• Pass - 30%
• Good - 45%
• Very good - 55%
• Excellent - 70%
• Outstanding - 85%

Question 4

What are PV Panels?

Answer 4

Photovoltaic Panels are used to produce electricity directly from sunlight.

Question 5

What is SUDS?

Answer 5

Sustainable Urban Drainage Systems:
- Designed to both manage the flood and pollution risks resulting from urban runoff and to contribute where possible to environmental enhancement and place making.

Question 6

What is a blue roof?

Answer 6

A blue roof is designed to attenuate storm water within a void. Which sits directly above the waterproofing layer and beneath a surface finish such as a vegetated green roof or hard landscaping.
- Designed to allow controlled attenuation of rain fall during heavy and storm events.

Question 7

What is a green roof?

Answer 7

Roofs that are partially or completely covered with plants or vegetation.

Question 8

How does life cycle costing work?

Answer 8

Process in which the project team assesses the cost of a building, building materials, or piece of equipment throughout its entire useful life.

Question 9

What is lean construction?

Question 10

Name some types of foundations?

Answer 10

• Strip Foundation
• Pad Foundation
• Raft Foundation

Question 11

Name some types of piles?

Answer 11

• Contiguous Piling
• Secant Piling
• CFA Piles

Question 12

What is Contiguous Piling?

Answer 12

A series of adjacent piles constructed to form an earth retaining structure as a cantilever or propped cantilever wall.
Consist of a row of successive unconnected cast-in-situ concrete piles constructed with small gaps between adjacent piles.

Question 13

What is Secant Piling?

Answer 13

• Formed by constructing reinforced concrete piles that interlock
• Often used as a cost-effective solution when short-term water retention is required.
• Are reinforced with either steel rebar or steel beams
• Typically, primary (female) piles are cast in situ, leaving space in between them. This is followed by secondary (male) piles being cut into the primary piles to for a continuous wall, generally with a typical interlock of around 150mm.

Question 14

Advantages of secant piling?

Answer 14

• Provide greater stiffness compared to sheet piles
• Can be installed with difficult ground conditions
• Less noisy than other methods of piling

Question 15

Disadvantages of secant piling?

Answer 15

• Vertical tolerances difficult to achieve for deep piles
• Higher cost than sheet piles
• Total Waterproofing is difficult to achieve in joints

Question 16

What are sheet piles?

Answer 16

Sections of sheet materials with interlocking edges that are driven into the ground to provide earth retention and excavation support.
Most commonly made of steel, but can also be formed of timber or reinforced concrete.

Question 17

What are sheet piles commonly used for?

Answer 17

Sheet piles are commonly used for retaining walls, land reclamation, underground structures such as car parks and basements, in marine locations for riverbank protection, seawall, cofferdams and so on.
